Fig. 1A–B.

(A) Anterolateral and (B) posterolateral views of the humerus and scapula in the 3-D model are shown. The glenosphere is lateralized by an 8-mm resin block (green). To align the humerus and scapula, two coordinate systems were defined (red lines, scapula coordinate system; white lines, humeral coordinate system). The subscapularis and teres minor are each represented by three lines (subscapularis, blue lines; teres minor, green lines).
